Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613950, here are decompositions:

23 + 31613927 = 31613950
83 + 31613867 = 31613950
89 + 31613861 = 31613950
107 + 31613843 = 31613950
131 + 31613819 = 31613950
149 + 31613801 = 31613950
167 + 31613783 = 31613950
233 + 31613717 = 31613950

Showing the first eight; more decompositions exist.
